ChemSketch:
free software - Advanced Chemistry Development, Inc.
Molecule drawing and modeling program. Download for free. "In
the past four years the Chemsketch drawing package has attracted
enthusiastic comments from its users and it has been
acknowledged to be the most powerful and easiest to use
molecular structure and chemical drawing tool available today."

CHEMBIOFINDER
Search - CambridgeSoft Corporation "At the moment,
this database contains an eclectic 2500 compounds. We are
particularly well represented in small biological molecules,
including sugars, amino acids, nucleic acids, and steroids. We
also have large selections of drugs and dyes, with particular
emphasis on household items."

"MINIMUM" Level: 9th Grade

Analytical
Chemistry Basics - B. Tissue, SciMedia "The goal of
this on-line course is to provide the user with an introduction
to some of the fundamental concepts and methods of analytical
chemistry." Chemical equilibrium, Titration, Electrochemistry,
Spectroscopy, Separations.

"MINIMUM" Level: graduate

Spin
Trap and Magnetic Resonance Database - NIEHS, NIH
Multimedia. "These services provide the basics for an Magnetic
Resonance database on the Web. While it now contains all 9000+
records originally contained in the Spin Trap Data Base, we have
expanded the format to include more information".

DIY
Glycolysis - J. Maber, Univ. of Leeds Practically
everything from the beginning with glucose to the more advanced.
"If you memorise the sequence of reactions from the textbook and
simply enter them, you will learn very little. In fact you will
find that you will sometimes learn more from choosing the wrong
reactions! Each time you choose the wrong reaction type, a page
of text will tell you whether the reaction is impossible,
undesirable or simply not the way it has evolved. More
important, it will tell you why. Hopefully you will discover
that glycolysis is not simply a series of chemicals which you
must memorise but a finely optimised system for squeezing energy
out of glucose which has evolved over billions of years."

Metabolic
Pathways - Kyoto Encyclopedia of Genes and Genomes
Graphical pathway maps and ortholog group tables. "...an effort
to computerize current knowledge of molecular and cellular
biology in terms of the information pathways that consist of
interacting molecules or genes and to provide links from the
gene catalogs produced by genome sequencing projects."

The Large Hadron Collider (LHC) - CERN "To smash
protons moving at 99.999999% of the speed of light into each
other and so recreate conditions a fraction of a second after
the big bang. The LHC experiments try and work out what
happened."

The Sudbury
Neutrino Observatory "The Sudbury Neutrino
Observatory (SNO) is a 1000 tonne heavy water Cherenkov detector
under construction in INCO's Creighton mine near Sudbury,
Ontario. Located 6800 feet below ground, SNO is designed to
detect neutrinos produced by fusion reactions in the sun. SNO
will provide revolutionary insight into the properties of
neutrinos, as well as yielding constraints on reaction
mechanisms in the sun..."

Introduction
to Cosmology - NASA "...introduces basic concepts
in modern cosmology and describes the MAP mission at a general
level. " Topics include: Big Bang model; expansion of the
universe; theory of inflation; chemical elements origins; large
scale structure; Milky Way; life and death of stars, etc

Virtual Trips to Black Holes and Neutron Stars - R.
Nemiroff, Michigan Technological University "Ever wonder
what it would look like to travel to a black hole? A neutron
star? If so, you might find this page interesting. Here you will
find descriptions and MPEG movies that take you on such exciting
trips. These movies are scientifically accurate computer
animations made with strict adherence to Einstein's General
Theory of Relativity. The descriptions are written to be
understandable on a variety of levels - from the casually
curious to the professionally inquisitive. It is hoped that
students from grade school to graduate school will find these
virtual trips educational. "

THE HOT BIG BANG MODEL - P. Shellard, U. of
Cambridge, UK "This tour introduces the Big Bang cosmology
and its successes, while emphasising its incompleteness and the
areas in which Cambridge Relativity group members are working.
The key question that interests us, as we delve backwards in
time before the standard cosmology, is: Why was the universe the
way it was at one hundredth of a second?"
